What’s new in Decise

The first public Decise release. A native macOS visual editor for Next.js + Tailwind projects — select elements directly on your running app, edit them visually, and watch clean format-preserving diffs write back to your source files.

Editing

• Inline text editing on canvas with shared-template writes for repeated UI.
• Source-backed drag, copy, paste, delete, and bounded move flows for JSX that can be proven safe.
• Visual spacing and layout inspector with flex and grid controls.
• Typography editing with project-aware Google Font picker for editable font-family tokens.
• Native OKLCH color editors for backgrounds, text, borders, rings, and gradient stops.
• Source-backed background and gradient editing.
• Bounded ring, shadow, blur, backdrop blur, border width and radius editors.
• lucide-react icon picker with automatic import rewiring and prop preservation.
• Image source swapping with source-backed asset writes.

Design System

• Tailwind token extraction for colors, font families, type scale, radius, and spacing.
• Token search and in-place value editing.
• Google Font picker flow for editable font-family tokens.
• Explicit unsupported states for projects Decise can't resolve safely — never guessed edits.

Navigation

• Route-first Project Navigator backed by an engine manifest.
• Inline route filtering, pinned routes, recent routes, and bookmarked views.
• Parameterized-route presets so dynamic segments stay openable.

History

• Session undo/redo surfaced both in the History sidebar and via the native macOS menu bar.
• Per-edit provenance and checkpoint detail so every change is traceable.
• Restore any prior checkpoint from the history timeline.

Licensing & updates

• Ed25519-signed license keys with local validation and trial gating.
• Bundled trial sample project — a real Next.js + Tailwind + shadcn app, with every editor feature available.
• Stripe checkout and customer portal for purchases and subscription management.
• Signed, notarized macOS builds with automatic Sparkle updates — the next release arrives on its own.

Under the hood

• SWC-based AST instrumentation and Recast-driven format-preserving write-back.
• Shared-template editing stays truthful when multiple runtime instances point at the same JSX.
• Decise runs as a native Swift app with a WKWebView canvas, talking to a local engine over WebSocket.
